Cutting Aluminum foam core
Does anyone happen to know if a Chinese spindle, 4kw, would be able to handle cutting 1/8" aluminum foam core board? I have one small project I need to cut some windows out of it and bend it. The aluminum looks to be super thin and I'm sure that others cnc it, I just don't want to risk any bearing problems on my router.
Any ideas? Thanks, Chris |

I've just come inside from cutting 3mm PVC sandwiched between aluminium (ACM), I guess foam is easier.
I use a 3kw spindle, 2mm single flute at 800mm/min. If I was using a larger bit I would cut faster. Add a bit of air for cooling and leave the protective cling plastic on until after cutting seems to pull the 'hairy' stuff off. Good luck |

Spindle speed fastest (I don't know exact rpm). Up cut bit.
For miter joints i use a modified 90 deg cutter on the fold lines and cut not quite all the way through. To modify the 90 deg cutter I just ground the tip of so that there was about 0.5mm flat. |

Very nice! Do you place the presentation face face up or face down? Looks fantastic! Thanks for the help.
